Application filed. August 5, 1914:. Serial No. 855,315.

To all whom it may concern:

Be it known that I, PHILIP P. NUN- cnssnn, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Machines for Filling Dry Batteries,ofwhich the following is a specification.

. This invention relates to an improvement in machines for filling dry batteries.

In the accompanying drawings, Figure 1 is a front elevation of the machine partly in section at its top, and Fig. 2 is a side elevation thereof. Fig. 3 is a plan view of Fig. l, omitting the parts .beneath the top. Fig. l, Sheet 2, is an enlarged vertical sectional elevation of the upper'portion of the machine illustrating, particularly, the pneumatic control. Fig. 5 is an enlarged sectional elevation of the valves and valve' casing, corresponding in the main to Fig. 1. Fig. 6 is an end view of the pneumatic valve. Fig. 7 is a detail of the link mechanism through which the valves are reciprocated.

The machine as thus shown is designed to employ a pneumatic engine for operating the tamping mechanism, but otherwise the machine is constructed more or less after the pattern shown and claimed in a patent issued to The Nungesser Electric Battery Company, February 28, 1911, No. 985,691, and which was invented by me. Thus, F represents the frame which carries the working parts and is supported in upright position by any suitable means, as a wall to or other fixed support. The said frame is provided witha base B on a solid foundation which is adapted to withstand the constant tamping without being impaired, and has inwardly projecting arms a, a, a at intervals uponwhich the working parts of the machine are disposed. These parts comprise a table for the sectional foldable receptacle or inclosure 2 adapted to receive the battery can or jar in which the material is tamped; a hopper h adapted to receive the material with which the jars are filled, and

"a plunger P which operates through the bottom of the said hopper in the said jar to tainp the material. thereln. The said plunger is engaged with and operated by piston P in cylinder 0, and said piston is under pneumatic control as hereinafter described. The said rod is provided with a cushioning and lifting spring 3 for the plunger" as before, and a collar 0 on said rod serves as a point of engagement for a pawl 7 rigid with lever 8, pivoted at 9 and adapted to be tilted within limits to engage and disengage said pawl with said collar. Con trol of said lever is through the cord or wire 13 and the treadle 10 below, on which the foot of the operator rests to depress the same while a jar is being tamped and during which time the pawl is thrown back out of engagement or idle. But when the treadle is relieved by the operator the counterweight 12 on said lever 8 instantly reverses the lever and throws the pawl forward beneath the said collar, arresting the descent of the said plunger. By these means I am enabled to instantly suspend the tamping when desired and by the same operation the tamping rod P is raised clear above the jar to enable the jar to be removed.

The pneumatic portion of the machine is of an auxiliary character and comprises an engine with a cylinder C and piston P therein, and a pair of combined or unitary valves 1: and c which control the flow of air to and from said cylinder on opposite sides of the piston, as will now be seen. Thus, the said cylinder has two ports 15 and 16, respectively, in its side which communicate with the valve chamber C, and inlet and exhaust pipes 17 and 18, respectively, open into the said chamber. The two valves '0 and n, have refined adjustment upon a single tubular screw-threaded stem 20, Fig. 5, to get exactly the right working positions and relations in respect to the said inlet and exhaust pipes and ports respectively.

A cut-off valve o in the inlet passage or pipe 17 controls the pneumatic pressure to the engine, and the said valve is connected by cord or wire 22 with the treadle 10, so that said treadle serves the double function of releasing the pawl 7 and of opening the said valve '0 in the same operation. This automatically starts the tamper. A spring 23 is arranged to turn and close the said valve 0 when pressure by the foot of the operator is removed from the treadle 10; The same act liberates the pawl 7 and enables it to resume engagement with collar 0 as described and intercept the descent ofthe plunger. It will thus be seen that the control of the tamping mechanism proceeds from a source of power wholly outside of the machine, as from a line shaft or the like, and is localized in the machine through a stub shaft 24 supported in a standard or the like on the main frame F carryingla sheave or pulley 25 with which beltconnection can bemadefrom the said drive or line shaft.

Pulleys or sheaves on the line shaft will the speed of the said sheave 25 and may, therefore, be of a size corresponding to the speed wanted. An eccentric or crank 27 is fixed on the endof said stub shaft and connectediby an adjustable rod 28 with .a seg-;

mental lever 30 in the link connectionswhich eXtendto the valves, 1;, o; The said lever is pivoted between its. ends on a pivot 31 on a bracket mechanism 32 from the middle arm a of the main frame and behind the tamping rod P. The long arm ofithe said lever has a segmental slot 33- lengthwise in which spect to the ports which they COIltlOl-s It. follows as a result of the operation thatthe engine piston. P" is reciprocated and the tamping rod P therewith is operated so as to provide as rapid and as compact tamping in the battery jar as may be desired. Of course uniformity of tamping in a given jar and uniformity between. jars is a desicl' eratum in any case, and one ofthe advantages of the present machine over all others known to me is the speed anduniformity with which it does its work. Valves 7) and o are in the form of sleeves slidably mounted on the hollow stem 20 and are adjustably held .in place by nuts 21, and the upper end of the stem is open to permit the exhaust from port 15 to pass through the stem and out of an opening at the lower end of the stem and thence to pipe 18, see Fig. 5.

A peculiarity of this machine resides in the use of an independent source of power to operate the valves 1) and '0. In other words the movement of the valves is not dependent upon the reciprocable movements of the-pistonP and plunger P, but is controlled by the adjustable operating mechanism derivwith a'treadl'e, a valve controlling the flow of 'pneumatic energy anda stop adapted'to engage said tamper operatively connected with the said treadle.
